Need to post STL files twice

[david.mcdonald6GYJG]

When I export an STL file,,, the first time takes forever or never posts at all. When I export it a second time (different name), it posts immediately. Why do I need to export twice to get one file?

I have been noticing the same problem with exporting .F3Z files, first one just hangs and doesn't work, second time it happens very quickly..

I don't see this with .f3d export though.

You shouldn't need to do this it must be a bug
